The1904 World Series was the scheduledchampionship series ofMajor League Baseball's (MLB)1904 season. However, it was not played. It would have been contested between the champions of the two major leagues—theNational League (NL) and theAmerican League (AL)—as had been done in October 1903, the first modernWorld Series.

The league champions in 1904 were theBoston Americans (now theBoston Red Sox) of the AL and theNew York Giants (now theSan Francisco Giants) of the NL. Boston had clinched their second consecutive AL pennant, while New York won the 1904 NL pennant by a wide margin, 13games ahead of theChicago Cubs. With still no formal arrangement in place between the two leagues regarding the staging of the World Series, the Giants under ownerJohn T. Brush refused to play against a team from what they considered an inferior league. The resulting criticism from fans and writers caused Brush to reverse course during the offseason and lead the effort to formalize the World Series between the two leagues.

In the first modern World Series in 1903, as well as several postseason series between the National League and theAmerican Association in the 1880s (sometimes referred to as "pre-modern World Series"), the rules for a given season's "World's Championship Series" had been whatever the two participating clubs had agreed upon. The World Series was not a compulsory event and was not governed by an authoritative body. Thus, when the Boston Americans defeated the National League championPittsburgh Pirates in the1903 World Series, the contest was arranged directly by the two champion clubs, not by the leagues themselves.^[1]

During this time, there was an intense business rivalry between the two leagues, especially in New York.^[2] Duringspring training in March 1904, New York Giants ownerJohn T. Brush said "there will never be a series" between the New York-based teams—his Giants of the National League and the American League'sNew York Highlanders (now theNew York Yankees)—in response to a preseason offer from Highlanders co-ownerFrank J. Farrell.^[3]

In July 1904, as reported inSporting Life, Brush stated that his NL club would not play the AL club "if each wins thepennant in its respective league", in contradiction of a preseason agreement for a championship series between the leagues.^[4][5]: 57

The Giants won the NL by a wide margin (13 games). The club then stuck to their plan, refusing to playany AL club in the proposed "exhibition" series (as they considered it).^[5]: 58 Giants managerJohn McGraw, who had personal animosity with AL presidentBan Johnson, said that his team was already the world champions because they were the champions of the "only real major league".^[2]

The AL race went down to the wire. By July, the Highlanders were just1+1⁄2 games behind the Boston Americans.^[6] The Highlanders then temporarily took over first place on October 7 when they defeated Boston.^[7] But the Americans won three of their four remaining games to clinch the AL pennant, and finished1+1⁄2 games ahead of the Highlanders (who lost three of their final four games) in the final standings of October 10.^[8]

Stung by criticism from fans and writers, Brush drafted rules that both leagues adopted in mid-February 1905.^[9] The rules compelled the two winning clubs to participate and governed the annual determination of sites, dates, ticket prices and division of receipts. These new rules essentially made the World Series the premier annualMajor League Baseball event.

Boston slumped in 1905, while New York repeated its NL championship and won the1905 World Series against thePhiladelphia Athletics. The two teams eventually met in the1912 World Series with the Red Sox winning in eight games (Game 2 was a tie). The Series has been played every year since except1994, when a 232-day-longplayers' strike ended the season in mid-August.
